Abstract (en)
The invention relates to a process for producing olefins from a feed stream containing hydrocarbons by pyrolytic cracking of the hydrocarbons in a steam cracker furnace, said process comprising feeding the hydrocarbons-containing feed stream to a tube in the convection section of the steam cracker furnace; pre-heating the hydrocarbons-containing feed stream in the convection section; feeding the pre-heated hydrocarbons-containing feed stream to a tube in the radiant section of the steam cracker furnace; and heating and pyrolytic cracking the hydrocarbons-containing feed stream in the radiant section resulting in an effluent containing olefins, wherein: at least part of the energy used in pre-heating and heating the hydrocarbons-containing feed stream through indirect heat exchange in the steam cracker furnace is provided through indirect heat exchange between an electrically heated gas outside the tube and the hydrocarbons-containing feed stream inside the tube in the steam cracker furnace; and at least part of the used electrically heated gas is electrically re-heated and then re-used in said pre-heating and/or said heating.
